Abstract (en)
[origin: US2018219597A1] A base station device includes a frame generator circuitry that generates a first training frame used for receive beam training among frames used for beamforming training, a beam controller circuitry that sets a beam used to transmit the first training frame to an omnidirectional mode, a transmitter circuitry that transmits the first training frame at the lowest MCS rate of IEEE 802.11, a receiver circuitry that receives first and second response frames from a wireless terminal device that has received the first training frame after a determined period since transmission of the first training frame, and a frame determiner circuitry that determines whether the first response frame is a response to the receive beam training. In a case where the first response frame is a response to the receive beam training, the beam controller circuitry sets a beam received by the receiver circuitry to a directional beam, and the receiver circuitry receives the second response frame with a directional beam.
